Step 1Remove the yellow seal. (If not, the printing effect is blank) | NOTICE:DO NOT peel off plastic sealing film, because it will be automaticly punctured when the printer works. | Step 2Install the ink cartridge to the printer until it clicks into place. (If you don't hear "clicks" sound, the ink cartridge couldn't be recognized) If the printer interface prompts “Non-Brother ink cartridge”, please click OK and then use our LCL ink.(Otherwise, the printer will display no ink or after printing a few pages, it displays no ink) |
